@ladyaceintx1 Thanks for your reply. I'm trying to picture a metal bookend that would feel good ....! Could you post a photo ? But I do find a lumbar roll is helpful in the car. I am pretty thin and petite also and I do wonder if our body types might be more sensitive to our spines feeling differently. I was just finally approved to start PT ( 5 1/2 months out ) , and my surgeon is hopeful that will help things along.
